[REG 5.4.2->5.7.1]: When a folder contains a shortcut to a broken network share it can hang briefly when navigating to that folder in the dialog. Even though it is using a system dialog in this case so it should not be using Qt for this.

The reason for this seems to be because the FolderListModel is still created and this has a file system watcher in place too which can cause some complications even though it is not needed.

To reproduce, create a shortcut to a network shared folder in a directory. Then disconnect the network from the share (not from the machine that you are running the test from). Open the standarddialogs example from Qt Quick Controls and navigate to the location that contains the shortcut and observe that it hangs briefly. With the network connected it is fine.
